A grassland area, similar to World 1 from the previous New Super Mario Bros. games, containing mushroom hills and the castle of the princess. It has been taken over by the Koopa Troop and is slowly transformed into Bowser's image until eventually being surrounded by a tornado. By the time the player reaches the castle grounds, it has been transformed into a lava-based area. Princess Peach's castle remains mostly unchanged on the outside (the flags now have Bowser's symbol on them) but on the inside it is similar to Bowser's Castle from previous installments.
